Rated 5 out of 5 by NovaScotia from Great fan for cooling the house...We live in an area where it can be very hot during the day but it is always nice and cool at night... the problem being there is no breeze at night to bring the cool air into the house. We bought 6 of these fans during the recent heat wave and had them running all night and they really did the job well! The house was beautiful and cool in the morning and we were able to get a good night's sleep with them on. We even find the exhaust feature handy (you have to turn the fan around for it to exhaust) when doing a lot of cooking one day. We just put it in the kitchen window on exhaust and it really made a difference, removing the cooking steam and odours (we don't have an exhaust fan over the stove). We highly recommend these fans and also shopping online at Wal-Mart. Our order was shipped quickly and arrived in excellent condition. :-)

Rated 5 out of 5 by Jacquie from Excellent fan!I bought this fan in hopes to cool off a room in the house that I have never been able to cool. Its was really easy to install, fit in the window with the screen still on, and is really quiet! The only suggestion I would make was that I wish I could control the direction of each individual fan, and didn't need to flip the entire unit around in order to get the fans turning the other way.

Rated 4 out of 5 by BobbyGGG from I love this fan!This fan is definitely more expensive than your average conventional fan. But it is worth every penny! My room faces the west so it begins to get burning hot at around 6pm during the summer time. The air circulation is horrible in my room and the warm air gets trap in the room for the entire evening. The thing is that the outside air is cool and breezy, so it is only hot in my room. What i like about this fan is that it is position at the window (saves floor space). What this means is that it pulls the cool air from the outside into the room instead of a regular fan that pulls in the warm air in the room and blows out the warm air back in the room. After turning the fan on 10 mins, i can immediately feel the room has gotten cooler. What I would suggest getting along side with this fan is those timer outlet. It does get a little too cool into the night so sometimes I have to wake up in the middle of the night to turn it off.

Rated 5 out of 5 by ehyoyoeh from Poor man's ACThe window fan was easy to setup and runs more quite then most fans I have used. I turn it on a couple hours before bed and the room cools down nicely.

Rated 5 out of 5 by kellylynn from Working greatI read reviews and this fan is great, but one needs to understand this fan would preform best on a cool summer night not during the day or anything when it's hot outside (that would just be bringing in hot air) I live in a 2 bedroom townhouse and the upstairs gets insanely hot and when I open the window at night the breeze hardly comes in, what this fan does it bring in the cooler air better. Only downside is with both the extensions in it's still about 3 inches too small for my window but I did not measure so it's my own fault, Since this is just a fan and not an air conditioner I dont mind the 3 inch gap at the top. very easy to take down when not in use. I have yet to try exhausting the stale air out but when its humid out one night I will try
